RESERVE-STORAGE VALVE.

Specification of Letters Patent.

Patented Aug. 20, 19118..

Application led October 11, 1917. Serial No. 195,948.

To nl] i/ifm/ 'it 'may concern:

Be, `it known that I, Annan IC. OLANDER, a citizen 0f the United States, residing at Billings. in the county ot Yellowstone and State ot Montana, have invented certain new and uset'ul lmproveiiients in Reserve Storage Valves, otwhich the following is ya specification.

This invention relates to valves and has more especial reference vto a reserve storage valve t'or use in connection with tluid fuel tanks.

' The invention has toi'lits principal ohject to provide a valve. which can be readily applied ovci' the outlet means ol a tluid 'fuel storage tank with but slight alteration thereto, whereby a quantity ot' t'uelwill be always h'eld'in reserve in the tank andfwhen `the occasion so requires. may he allowed to [lowl therefrom, thus enabling the engine or other apparatus receiving thetue'l to continuel to operate Jfor a short period ot' time: the device.` obviously, being especially desirable for 4use, on motor driven vehicle l'uel tanks. permitting the vehicle to reach a supply station or the, like whereupon the tank can be rofilled.

Among other aims and objects of the invention may he i'ecited. thc provision of a device of they elia'actei' mentioned with a view to (,:oinpaetness` and in which the ninnher otl parts are t'ew, the construction simple, the, cost ot' production small` and etliciency and operation high.

The iiiipi'oveinents in the details and arrangement of parts will be apparent t'i'om an inspect-ion ot the accompanying drawings, iii connection with the, specific description hereinafter contained, and herein-the pre,- Vleri'ed embodiment ot the invention is disclosed for the purpose of iiiiderstaiuling ot' the saaie.

ln the drawings z- Figure, l is i vertical section through a l'uel tank provided with the improved valve, and

Fig. 2 is a vertical section through a slightly modified forni ot valve.

llaving` more particular reference to thcimparting a full ed filling opening 3 formed in the top thereof.

Arranged over the outlet opening 2 is a vertically disposed cylindrical valve cage 4, the upper end of which is opened for a purpose which will be subsequentlyV apparent. A valve comprising a hollow cylindrical body is slidably received in the cage e and has the lower portion thereof ground and shaped to permit seating of the saine upon t-he marginal edge of a bushing 6,'the said bushing being screw threaded and turned into engagement with the outlet opening 2. ln this connection, it is to be noted that the cyliiulrieal va ye 5 is of a length slightly f less than its cage l and has movement of the same with relation to the cage limited h v means ot a flange T formed upon the uppei' marginal edge of the said cage. A. pin El is passed through the upper end of the valve ."i and is engaged by thc adjacent end ot'y a contractile coiled spring 9, the lower end ot' whieh is engaged with a `similar pin l() passed through the upper end of the screw threaded bushing,r (l. By so engaging the valve' it will be readily understood that the saine will he normally maintained seated upon the bushing (l and as aconsequence, will permit the l'low ot fuel by the saine, thereby maintaining a predetermined reserve quantity of fuel in the tank Jfor use in emergency..

cap 1l is turned into engagement with the screw threaded opening 3 and is provided with a concentric opening through which a cord 12 is passed downwardly into engagement with the Cross pin-S. To prevent displacement ot the cord l2 a knob 13 may he and preferably is arranged upon its t'i'ee extremity which as will be noted, is positioned exteriorly of the tank, l. A spindle llt is carried by the. 'cap 11 and is adapted to have the exterior portionof the cord 1Q coiled the aibout whereby thesa'ine will be maintained in a position convenient' tothe user and also to hinder removal of they/fv cap ll until the cord l2 has been disengaged there/trom and the valve 5 permitted to close. il. spring clip 15 is alsofarranged upon the cap 11 and serves asfadditional means t'or locking the cord anev hence, the valve 5 in an open or partially I'pened position to permit the passage ,ot the entire 'quantity of YFuel Afrom the tanlril.

In Fig. 2 I have shown a slightly `modified form of valve, the same being particularly adaptable for use on tanks containing heavy liquid fuel. In this particular embodiment, the valve cage if 1s provided with diametrically disposed vertical slots 16 through which arms 17 carried upon the upper end of the. valve 5 are received. Other arms i8 are arranged at diametrically opposite points upon the bushing 6 and serve as means for receiving certain of the ends of contractile coiled springs 19, the remaining ends of the said springs being secured to the arms 17 and serving as means for normally maintainin the valve 5 seated over the outletopening of the fuel tank. By so arranging the-springs, it will be understood that an unobstructed passage for the bulk of the fuel flowing from the tank is provided. I,

From the foregoing, 1t will be appre 'ciated by Workers skilled in the art that with my .improved valve, a reserve quantity of fuel will be normally maintained in a fuel tank, thus enabling the device receiving the fuel to operate for a brief period of time subsequent to the discharge of the bulk of fuel therefrom. The device may be advantageously used upon the fuel tanks of motor driven vehicles wherein it frequently occurs that the supply of fuel from the storage tank is exhausted before the operator notices the same. With my improved device, by pulling the cord 12 upwardly the valve Will be raised from over the outlet opening in the tank, thus allowing the reserve quantity of fuel to flow by the sameto the engine. The construction of the valve is such as t0 avoid' the hindering of the passage of fuel through v modification as is Within the scope of my claims, I consider Within the spirit of myin vention.

I claimri l. In combination with a receptacle having an outlet opening therein, a cage over said opening, a .hollow cylindrical valve slidably received in the cage, the upper end of said cage being fianged for limiting movement of said valve therein, and means engaged with the valve for normally maintaining the same over said outlet opening for reserving a predetermined quantity of fuel in said receptacle.

2. In combination With a receptacle, hav` ing an outlet opening therein, a cage over said opening, a hollow cylindrical valve slidably received in the cage, the upper end of said cage being bent to form a flange for limiting movement of the valve therein,.

spring means engaged with the valve for normally maintaining the same over said outlet opening for reserving a predetermined quantity of fuel in said receptacle, and means connected to the valve and eX- tending exteriorly of the receptaclefor fa cilitating operation thereof.

3, In combination with a receptacle,ihav-' ing a filling and an outlet' opening therein, a valve cage arranged over said outlet opening, a hollow eylinldrical valve slidable 'in said cage, the upper endof the cage being flanged. to limit movement of the valve therein, spring means engaged 'With the valve for normally maintaining the same seated over said outletopening for reserving a predetermined quantity of fuel in said receptacle, a closure receivable in the filling opening, a

.cord passing through theclosure into engagement Wlth said valve, and means on the closure engageablewith the cord for locking the same and maintaining the valve in adjusted position.

In testimony whereof I affix my signature hereto.
